IMPROVEMENT IN FLOUR-SIEVES.

Speciii cation forming part of Letters Patent No. 210,341, dated November 26, 1878; application filed September 24, 1878.

To all 'whom 'it may concern:

Be it known that I, JOHN H. LYNCH, of the city of Baltimore and State of Maryland, have invented certain Improvements in Flour- Sieves, of which thefollowing is a specification; and I do hereby declare that in the same is contained a full, clear, and exact description of my said invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates, first, to the combina- I[ion of a flour-sieve and a removable barrel cover or lid; and, secondly, to the peculiar construction of the sieve, as will hereinafter fully appear.

In the description ofthe invention which follows reference is made to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a longitudinal section of the invention. Fig. 2 is a transverse section of the same on line x y of Fig. 1, looking in the direction of the arrow. Fig. 3 is aplan of the invention, a portion ofthe same being removed.

Similar letters oi' reference indicate similar parts in all the views.

A is the barrel cover or lid, having an opening, a, about centrally thereof; and B, a box secured to the upper side 'of the lid, and provided with a removable top, C.

The opening a in the barrel-lid is covered with a piece of wire-gauze, D, rigidly secured to said lid.

E is a brush, consisting of a skeleton frame, b, to which the bristles c are fastened, confined in the box B, between the wire-gauze D and the top C, and adapted to be slid within the said box by means of a handle, d, projecting through a slot in the side of the box. The handle d may, however, pass through one end of the box B, or the brush may have a handle on either side thereof, if preferred.

The top C of the box has an opening, c, therein, and a hopper, F, supported by brackets f, and located directly over the said opening into which the flour to be sifted is placed.

In Fig. 3 the invention is shown without the top O and hopper F.

The our to be sifted is placed in the hopper F, and passes through the opening c to the box B, and thence to the kneading-trough, upon which the device is temporarily placed, the brush during the sifting operation heilig moved rapidly backward and forward to facilitate the passage of the flour through the wiregauze and reduce any lumps of caked ilour that may be arrested by the same.

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent of the United States, is-

The hopper F, removable cover C, box B, and brush E, having its handle d projecting from said box, and adapted to be'reciprocated in a slot formed in a side thereof, combined with the barrel-lid A, having the opening a covered by gauze D, rigidly secured to said lid, substantially as and for the purpose specified.

JOHN H. LYNCH.
